PROCESS AND MACHINE FOR CREASING.

Application filed JanuaryfiO, 1922. Serial No. 532,820.

To ill i /.007 it may concern:

Re i t known that we, CLAUDE H. HALL a d Gunner lZNUDSEN, citizens ofthe United I and residents of'Baltimore city, in the Ftate of hlaryiand. have invented a new lrocos; and hilachine for creasing, ofwhich the following is a specification.

our in ention relates to improvements in reasing. and has for its objectan improved in process reasing and a machine for accomplishing the same.

lu the ordinary method of creasing, dry heatin means is used, such as atable heated flame, which is not constant heat at a pre-determinedtemperature, but some times get so hot as to burn the fabric, which withmohairsand other stiff fabrics does not give the sustained creasedesired. To overcome this difiiculty is one of the objects of ourinvention.

A further object of our invention is the pro ess and means foraccomplish ng the turning, soften ng, holding turned and drying an edgeof fabric.

30 operated upon at a constant and pre-determined temperature.

Our invention consists of the novel process, method and appliances formaking permanent creases in fabric, as hereinafter described. themachine of which is illustrated in the accompanying drawings, but it isunderstood that changes variations and modifications may be resorted towhich come within the scope of the claims hereunto appended.

In the drawings of the herein described embodiment of our invention,Figure 1 is a side view in section taken through 1-1; Fig. 2, is a planview. Fig. 3, is an enlarged view of a portion of the machine takenthrough 3-3 and Fig. 1, is an enlarged view in elevation of the treadlelooking mechanism.

Similar numerals refer to similar parts throughout the several views:

1 is the table, the back of which forms a steam jacket 2. Within steamjacket 2 is auxiliary steam passage 3. 4 are orifices connecting withauxiliary steam passage 3 and directing the steam from said passagetowards the creasing to be done.

A further object of our invention i's'the v :3 is a die over which thecreasing is done. 5 are the edge turning dies, said dies being(flIl'lGCl by ross heads 7 operating between guides 8. 9 is the scrollplate in which are cam slots 10 and circular slots 11, in which work capscrews 12 to hold the scroll plate in place. The lateral motion of thescroll plate being confined by rollers 13 operating on studs secured totable 1. 141 is a handle on thescroll plate.

()n cross heads 7 are pins 15 carrying rollers 16. Rollers 16 areoperated by cam slots 10 upon a circular motion of scroll plate 9operated by handle 14, thus operating the edge turning dies to andfromthe work operated upon. 7

Die 5 is carried by arm 17 journalled to the table and ha handle 18 foroperating. Ann 17 is normally'kept'open as shown in by spring 19. 20 areclamping bolts operating through cross heads 7 which cross: heads areprovideo with slots to permit of movement with reference to said bolts.Bolts: are secured to equalizing bars 21, which bars are operated bytension rod 22. 23 is the foot lever fulcrumed at 24C'and operatestension rod 22, and is held down in clamped position by catch 25 and iskicked out of locked position by foot ki'ck off 26. 27 is a bumper. 28is a-sprin'g tending to maintain foot lever 23 in up position, therebyreleasing the clamping bolts 20.

33 is a steam valve admitting auxiliary steam passage 3 and through theorifices as desired. 29 is the main steam supply one branch going tovalve 33 and another branch going into jacket 2 to a point well withinthe same. is a drain from the steam jacket which is connected with adrain from the steam line and goes to trap 31.

are gauges between which the fabric to be operated upon is placed.

The operation of our invention is as follows The fabric is placedbetween gauges 32. By means of handle 18, die 5 is brought down on thefabric pressing it on to table 1 which is maintained at a constantpre-desteam into of handleadmitted through valve 33, steaming thefabric. then by means of lever 23 and bolts 20, dies 6, clamp the fabricunder and over the edge of die 5. forming the crease in the fabricpreviously softened by the steam treatment. The fabric is held in thislatter position until thoroughly dried.

Having thus described our invention. what we claim and desire to secureby Letters Patent is l. The process of creasing consisting of turningthe edge of a fabric and pressing the same, maintaining said fabric at apredetermined temperature above operating room temperature and whilebeing so pressed admitting steam on to said fabric for a brief period oftime.

2. In combination in a creasing machine. a steam jacketed table carryingmeans for creasing goods. creasing means carried by said table, andmeans of admitting steam directly upon the goods while in the creasingmeans.

3. In combination in a creasing machine, a steam-jacketed table carryingmeans for creasing goods, creasing means carried by said table. andmeans of admitting steam directly upon the goods while in the creasingmeans consisting of perforations in said table through which steam maypass communicating with a steam supply.

4. In combination in a creasing machine. a steam-j acketed table,creasing means carried by said table, means of admitting steam directlyupon the goods while in the creasing means consisting of perforations insaid table through which steam may pass communicating with a steamsupply, and means of controlling said steam supply independ ent of thecontrol of the steam in the steamjacket.

5. In combination in a creasing machine, a table provided with means ofheating the same to apre-determined desired point.

means of controlling said heating means and automatically maintainingthe same at said desired point, means of turning the fabric into creaseattached to said table. means of steaming the fabric as desired whileheld by said creasing means.

6. A creasing machine comprising, a steam jacketed table an auxiliarysteam passage within said jacket and communicating with orifices throughsaid table a cloth clamping means to hold clot-h on to said table, and acreasing means operating upon the cloth so clamped.

7. A creasing machine comprising, steam jacketed table, an auxiliarysteam passage within said jacket and communicating with orifices throughsaid table said orifices being disposed and pointed to direct steam onto the edge of the cloth being creased.

8. A creasing machine comprising, a steam-jacketed table, an auxiliarysteam passage communicating with orifices through said table. acloth-clamping means to hold cloth on to said table, and a creasingmeans operating upon the cloth so clamped.

9. A creasing machine, comprising a steam-jacketed table, an auxiliarysteam passage communicating with orifices through said table, saidorifices being disposed and pointed to direct steam on to the edge ofthe cloth being creased.

10. In a creasing machine. a steamjacketed table, an auxiliary steampassage within said jacket communicating with a spray-nozzle forsteaming goods being creased, and a cloth-creasing means secured to saidtable.
